Abstract: An insulation resistance detection circuit is coupled to a positive end and a negative end of a DC power source, and is used to detect a positive insulation resistance between the positive end and a ground point and detect a negative insulation resistance between the negative end and the ground point. A detection unit sets a first estimated resistance and a second estimated resistance, and acquires a first voltage based on turning on the switch and acquires a second voltage based on turning off the switch. The detection unit calculates a third voltage and a fourth voltage according to the first estimated resistance and the second estimated resistance so as to detect the positive insulation resistance and the negative insulation resistance when the third voltage is equal to the first voltage and the fourth voltage is equal to the second voltage.

Abstract: A power conversion device includes a power supplying terminal, a switching converter, a signal injector, a coupler circuit, a detecting circuit and a controller. After an input voltage is converted into an output voltage by the switching converter, the output voltage is outputted to a load through the power supplying terminal. The signal injector provides a signal. When the load is connected with the power supplying terminal, an operating parameter at the first end of the coupler circuit has a first variation value in response to the signal. When the load is disconnected from the power supplying terminal, the operating parameter at the second end of the coupler circuit has a second variation value in response to the signal. According to the detecting result of the detecting circuit, a switching action of the switching element is selectively enabled or disabled by the controller.

Abstract: The present disclosure provides a three-phase AC/DC converter aiming for low input current harmonic. The converter includes an input stage for receiving a three-phase AC input voltage, an output stage for at least one load, and one or more switching conversion stages, each stage including a plurality of half bridge modules. The switches in each module operate with a substantially fixed 50% duty cycle and are connected in a specific pattern to couple a DC-link and a neutral node of the input voltage. The AC/DC converter further includes one or more controllers adapted to vary the switching frequency of the switches in the switching conversion stages based on at least one of load voltage, load current, input voltage, and DC-link voltage. The converter can also include one or more decoupling stages, such as, inductive components adapted to decouple the output stage from the switching conversion stages.

Abstract: A connector for a system circuit board or a power module is provided. The connector includes a main body and an optical connection mechanism. The main body includes a first connecting terminal and a second connecting terminal. The first connecting terminal and the second connecting terminal are power contacts or signal contacts. The optical fiber connection mechanism is embedded within the main body. The optical fiber connection mechanism is disposed between the first connecting terminal and the second connecting terminal. Since the optical fiber connection mechanism is embedded within the main body, it is not necessary to specifically remove the optical fiber cable when the power module is detached from the cabinet. Moreover, the appearance of the product is more aesthetically-pleasing, and the maintaining speed and the product reliability are increased.
